I Made My Bike Camper Electric - 100+ KM Range (No Pedaling)
HTML-код
- Опубликовано: 11 авг 2022
- This spring I built a camper I can tow with my bike... Now I've modified it to make it electric with a huge range of over 100KM!
I make an DIY lithium ion EBike battery (51AH 48V battery for a 48V 1000W Ebike Conversion kit using BAK 6.1A 18650 battery cells), repair some flaws in the first design, add solar power and solar charging for more range and convert my bike to an ebike with an easy conversion kit.

I'm glad my battery building series helped you with the battery pack! You created something amazing here!
Awesome, I wish I had the skills to do this
@@shable1436 Dont wish, just learn how and do it.
@@JackNmD I wish I knew how to learn
@@JackNmDwish i had the money to even start
@@shable1436 you do have the skills you just showed you every step of the way just do it I am!
I loved the first build and couldn't wait for this ebike sequel!
I do, however, have some constructive criticism on the battery construction, and i do mean constructive. I'm not here to bash.
You said yourself you had never done this before, so I'd like to give you some advice as a seasoned battery builder. I did my own ebike conversion with a mid drive Bafang (id recommend mid drive for more torque, which you need with weight and hills) and built my own battery as well. I've built about 7kwhr of batteries for my off grid solar power system, as well as commissions for some friends.
Battery safety is paramount when working with lithium. It can be very dangerous if you don't take proper precautions/safety measures. We need to ensure the DIY battery community maintains a good reputation by focusing on safety. Battery fires are a terrible thing for individuals and the DIY community as a whole.
First, your retaining mechanism of hot glue. A lot of professionally made battery packs are indeed glued together, but they use a much higher strength glue (trust me, I've disassembled many lol) and at least some sort of cell holder. A physical spacer is important to keep the cells away from each other. If they are touching and somehow rub together (maybe the hot glue fails) enough to wear through the plastic wrapper, they can short out on each other. No bueno. We use abs plastic cell holders. Search eBay or amazon for 18650 cell holder. They are relatively cheap, and add a lot of structural integrity to a pack.
Second, lets talk about your soldering. The smaller soldering like the BMS leads looks fine, but your larger solder joints (like on the main positive and negative wires) looks. Well. Not great. Unfortunately solder joints arent like welds, you cant fix them with a grinder and paint.
Now here's what i don't like about them: it looks like they are cold solder joints. This is where the solder kind of just sits on top of a surface instead of really adhering. You can see this very plainly at 14:00 and 15:35 with the positive wire. The solder is kindof just sitting on top of the wire. What you want is for it to really soak into the strands. The way you want it to adhere to the nickel is for the solder to wet the surface of the nickel. (You want to look like its spread out like a puddle. if it looks like beads of water sitting on glass, its not right).
The way you achieve this is with heat and more solder. LOTS of heat in this case. Unfortunately, with the large 10awg wire you are (correctly) using, there is a lot of copper mass there that sucks the heat away. The small strand size also doesn't help, it will soak up more solder than a wire with thicker strands before its ready. You may even need a more powerful soldering iron (I know i do).
The reason this is an issue is cold solder joints are easily broken, and this is a bike. You're going over bumps. If a chunk of solder breaks off, it could go jumping around in the case, and possibly short something out. I recommend spot welding some more nickel strips to the positive and negative cells, and wrapping them around the wire before soldering. It helps.
Third, lets talk about the output terminal. XT-90s are great, I use them too. However, you want the other plug on the battery side (the one with the little green block or whatever. Its a precharge resistor). The reason is that the conductor pins in the connector on the battery the way you have it aren't physically separated. You can imagine what would happen if a piece of metal got stuck in there and shorted them out. You could start a fire if your BMS fails (ill talk about the bms in a bit). The other side of the connector though has plastic separating the two conductors. That connector should be used for the battery side, its much safer that way.
Fourth, the case. Its a great idea to use a waterproof case! Water and batteries don't mix! However, what happens if you have a cell fail, and the over pressure relief valve under the positive terminal vents? Well, now you have pressure building up in a sealed container. No Bueno. I recommend vents in the case. Vents may also be important for thermal regulation.
Fifth, and lastly, I want to talk about the BMS. Its a very important piece of safety equipment, as I'm sure you found out doing your research for this build. I'm very glad you have one! However, the one you have is a bit anemic. I wouldn't trust that bms with 10A, let alone the 50A it claims to be rated for. The only good thing about those BMS's is they're cheap. A BMS is a LAST RESORT safety device. If the BMS is the last thing protecting your pack, that means a lot of other stuff already had to go wrong, and youre in a tough spot anyway. As such, you don't want a cheap/flimsy BMS to fall back on. You also want a BMS with proper temperature monitoring (yours appears to just have a high temperature switch). A BMS with proper temperature monitoring will have a low temperature cutoff as well (its usually a single NTC thermistor for both high and low). You don't want to charge if the cells are below freezing.
Since you have the space, i recommend a larger (still 50A) smart bms from JBD or Daly. I use Daly, but would recommend JBD over them, I've been wanting to switch. These smart BMS's have proper temperature monitoring, better reliability, and convenient Bluetooth monitoring apps. In the apps, you can see individual series voltages, temperature, state of charge (you set capacity in Ah, and it counts Ah in and out), and any fault codes if it shuts down for some reason.
I hope you read this, and take what I've said under consideration. My goal here is not to demean you, but rather to help. I've made plenty of mistakes with my batteries (i saw a lot of those same mistakes in your video), and I just want to help others avoid those mistakes. We can all learn from each other and build better things!
Thank you. I was going to address the same points. Hopefully Drew sees this comment on time.
Well you saved me from having to write out all these points, so thank you :P. I would just add, I am a little concerned about heat buildup in that briefcase... Not sure if that foam is fire resistant, but depending on power usage and charging rates you could see a fairly large amount of heat building up which is detrimental to the battery lifespan and again is a fire risk. There is a reason why most large battery packs are ventilated properly or even have active cooling. A fully sealed container isn't a great idea...
Thanks for all this valuable information, I'm planning on building my first ebike battery pack soon and this will help. I have one question that you might be able to answer: do you think he is loosing a bit of efficiency and range by having the battery all the way to the back of the trailer instead of closer to the controller (on the frame or on a rear rack)? Or is the power vs wire gauge ratio enough that it won't make a noticeable difference? Thanks
@@MrRaptor2x In a word, no. Given the operating voltage is 48v and the wattage of the motor at peak is 1000w, you are only drawing around 21 amps. I'm guessing the wire is around 4 meters long, the resistance and voltage drop would be pretty negligible. A wire gauge calculator suggests using wire around 12AWG (3.31mm2).
Now its really hard to say what the gauge was he used but it looks pretty decent as 12awg isn't all that thick. That said, its better to go slightly bigger than too small. The other factor is operating temperature... Given the wires are in the open/air cooled and you are unlikely to be using the full 1000w constantly, you could possibly get away with wire quite a bit smaller. Again though, bigger is better.
It also depends on the type of wire (Aluminium vs copper etc). If i was building a project similar to this, i would be very tempted to mount the powered wheel on the trailer and just have the control wire attached to the bike. The problem with having the electric motor on the bike while the battery is mounted on the trailer is that bike is pretty much useless without the trailer. The added weight of the electric motor and control box would make riding the bike without assistance pretty terrible for any sort of distance. Whereas if the motor and controller was in the trailer the bike would be usable by itself, and if you added a tow point on other bikes the trailer could be used by friends etc on their bikes.
@@errolfeistl1705 the bigger problems with putting the power wheel on the cart have to do with handling i imagine. You want a symmetrical distribution of force, right? If you move the power wheel to the rear, you no longer have that. If you were to have force pushing on let's say the right wheel, it will want to turn left, and will put strain on the hitch, and stress on the driver to try to correct it. You'd really want two power wheels, one on each side. But then you have to deal with the challenges that come along with two power wheels, like separate controllers and one input.
Another problem is that moving the power to the wheels on the trailer is that you're now essentially trying to push a rope. The hitch has flex in it by design, so you can turn and stuff, right? If you try to push through that hitch, you have an unstable system (like trying to push a rope, or balance a pencil vertically on your finger).
It's a good thought, but I feel like the execution would be more trouble than it's worth. I think a better solution would be keep the power wheel on the bike, and build a second, smaller battery that mounts to the bike for when it's detached from the trailer. You'd only plug one in at a time, of course. Or, maybe a rear cargo rack on the bike that the original battery can mount to.
Re: the question @frenchcat asked, I agree with you Errol. I believe I remember him saying he used 10awg, but I might be mistaken as it was quite late lol. But yeah, 10 or 12 awg is fine for this. There will be /some/ power loss due to voltage drop, but I don't think it would significantly impact range.
Man, you siphoned away all the coolness in the world, by being a master builder, electricity wizard AND a rock star. Keep it up!
Watching the battery construction really stressed me out man. Crazy cool that you built this project yourself, but if you had ever seen a metal fire, specifically lithium batteries, I think you would have built that more safely.
Of all the suggestions other people made, battery spacers would be my biggest suggestion. A better BMS would be a close second. Thermal problems creates a positive feedback loop with lithium. That pack could totally be made safe with a few changes.
But yeah, awesome video and video making skills. The rest of the project seems awesome.
I know the battery freaked me out. The lack of cooling etc as well. jsut seems like a bomb one day when its charging lol
What are you trippin about. They're 6.1A cells with 17 in parallel so a max of 100A and his BMS is 30A and his controller is 50A so even if he has some bursts that his BMS doesn't trip (usually 3 seconds) the absolute max he can pull is HALF of the cells capabilities. Cells run at half their rated discharge rate usually don't heat more than 15 degrees beyond ambient. Even at 5A these cells run continuously will only hit 45C in open air so I think its fair to say that 3A continuous (which is impossible for him to pull, the max he could do continuous is 2A) would maybe get to 45C
@@ericklein5097 15:36 - cold solder joining that wire, almost 'tacked' like a tack weld, which doesn't translate well to solder, which needs to flow hot. Electrically and spec wise it might be fine-ish, each to their own, but it does seem bit of a hazard. Makes for an interesting YT video, but I'd personally just carry a few purpose-built battery packs.
@@MattExzy I'll definitely agree with that part, thats part of the build where a 150W-200W iron is absolutely necessary. I recently bought one and holy shit has it made everything so much easier when it comes to flowing solder on big heat conductors. Saves me so much time. Took me like 30 minutes to solder terminals to an HP DPS power supply and with the big iron it took me about 3 minutes for both
Awesome project! I would like to suggest a few things concerning safety, don't run the balance wires on the battery pack directly on top of the razor sharp tin strips, a bit of pressure from the weight of the battery pack combined with viberations could easily cause a short. Use fish paper (is intended for this application) and high temp capton tape to protect and secure everything, I try to have at least 2 barriers between all live parts, just the heatshrink/wrapper is not durable and will not last when one cell goes bad with high internal resistance causing the cell to get hot while charging and discharging. I also like to add fish paper donuts around the battery button top before welding, since the wrapper is the only thing seperating + and - there. Also wear safety glasses when constructing a pack like this, mistakes can happen, a pack like this is easily able to send molten metal flying in your face. I'm sorry for being one of those complaining safety guys but these packs have so much energy stored in them, it's no joke. If you cause a short and it reaches thermal runaway, it will completely go up in flames and you will not be able to extinguish it in any way.
Thanks for the safety tips, I will take take those into consideration for the next one! Thanks for watching!
you can glue it in place that way it cant rub around
@@DrewBuildsStuff DIYperks made a similar powerbank, which had some additional safety features: ruclips.net/video/adY-S8AH_Jc/видео.html
I'm no electrician, but the extra layers around the batteries looked sensible.
you should figure out a way to incorporate those safety cut-off switches when you're using the brakes the last thing you want is the motors to come on when you don't want them to such as on a steep grade when you're trying to use the brakes to stop at the bottom but you have to pedal to shift down to a lower gear. I'm assuming it's got a pedal assist sensor which is what that switch probably turns off there are definitely times when you don't want the pedal assist to kick in such as when you're doing maintenance on the wheels or drivetrain and your hands are down there. at the very least you should have a manual switch on the handlebars. you can always manually disconnect from the battery for maintenance when you're stopped, but it's difficult to do that in an emergency while on the bike, such as that situation where you're in a descent and you're trying to stop but the motors are still "assisting" I say that never having used those motors before for all I know they have an automatic cut off if there's no resistance at all (which they should, like in the situation where you lift the rear wheel up off the ground and the wheel rotates a little bit which turns the pedals, or if you're on a descent and you're going faster than the wheels are capable of assisting) something else to consider in this situation is regenerative braking. I'm not sure if the hub motors you bought support it. but I know that EUCs are basically a hub motor with a controller that is designed to maintain balance. one of the issues that they have is that when they're fully charged if you try to brake you can overcharge the battery with the regenerative braking causing it to completely cut out which is a really bad situation since they rely on the motor being on to keep you balanced. I just recently I watched the video about trailer stability, which showed the effects using models on a treadmill and by placing weight in various places on the model. you want to make sure the weight is as balanced across all of the axles as possible. too much weight at the back of the trailer means that the hitch wants to lift up which takes weight off of your rear wheel which means you don't get as good traction on the drive wheel causing an instability. too much weight to the front of the trailer means that your front wheel will lift giving you less stability in a climb and for steering which is what causes the speed wobbles. but the same thing can happen without a trailer too if you have too much weight over the back wheel then the front end will lift on a climb and you have to compensate by moving your body weight as much over the front wheel as you can.
I'd say you're more of a constructive comment safety guy compared to most of the 'you should've done xyz'. 👍 For being supportive. The balance leads chafing risk and the fish paper tip were worthwhile comments.
I like the idea a lot! As an electrician it was very uncomfortable to watch the battery assembly part, I really suggest separating the cells with air/kapton tape, especially the terminals before you start using the iron (you mentioned that, but did not cover them later either). The nickel strip you used looks quite thin, usually we sandwich some copper between the cell and the nickel so the connections wont get hot as fast. Also, heat shrinking the balance cables to the bare terminals/nickel strips is super dangerous, they are sharp and can cause short super easily. Many errors I witnessed here, sorry to be the one to warn you.
I really think this battery is dangerous, please fix these, there is too much chance for this to catch fire, especially dangerous that you are sleeping next to it.
What uncomfortable, it was perfect
Agree. The worst bit is the lack of an insulating gasket ring under the nickel strip on the positive connections. The only thing stopping a short is the very thin bit of cell insulation around the top edge. This could easily wear away with vibration or shrink back with heat.
By glueing the battery together, the only thing stopping it falling apart is the thin cell insulation (barring the shrink wrap). This is inadequate, especially for a battery that with experience harsh vibrations. Plus any damage to this cell insulation risks the shorting issue described above.
Lithium batteries provide their own source of heat, oxygen and fuel. They are extremely difficult to extinguish should they catch fire. This pack needs to be remade with cell holders and the proper insulation.
Question is it possible to have a alternating power source in a trailer just incase that it fails or dies
@@jayashreepatil6250 your comment demonstrates your lack of actual understanding of what is going on here.

@@DrewBuildsStuff glad to see you went ebike.
The foam in that case may prevent rattling, but you need to keep it cool as well. The black also absorbs uv heat. I love your channel!
I've seen other battery builds that put fans in the case to keep the batteries cooler under load or charging.
Woooooooooooow!!!!! You're living my dream life, riding bike, traveling as a campist, and playing good music!!!!! Congrats bro!!!!!
"Campist", there's a "thank you word " lol I like it a lot !!! Excuse me while I plagiarize you.....
i was a part of a solar car team in college & we used that same battery set up … but with over 5,000 of them. cool to see that design being used again. great build
This is simply amazing, love the camper build and the E addition has raised it way up.
This guy is a well rounded dude. If I ever attempt to make something remotely like this I'll follow this video.
Leave the battery building to a professional.
I gotta give you props for putting that much effort and money into that project, something I might do in the future if possible
For years I have been on the verge of building a tow trailer for sleeping for my motorbike and sidecar, though my first idea was for it to be for solo motorcycles; my plan was to taper like yours except sharp at the front end, and to have the door at the wide back end where you sit under the hinged up door to brew coffee etc... lovely to see what you have done.
Mark D Phillips.... Sussex England.
This is absolutely INSANE! I just finished electrifying my bike, but this video has inspired me to go out and possibly make some more modifications or additions! I think the idea of an electric camper bike is just so fun and unique.
Hell yeah it is I'm building one step by step just like this one except I might go like a foot longer... Kudos on the battery too that is the hardest part I know they sell 72 volt batteries triangle shaped for about 600 bucks not nearly as powerful as this one that 48 volts it's the amp hours that matter
You should add a built-in vibrator at the corner if you wanna jack off and possibly bust a fat nut while the e-bike is running. I've felt this kind of vibe while running away from authorities because of public masturbation and some other crimes.
What a vibe :D
Jeez… that was riveting! I loved everything about your video - science and engineering combined with escapism, self sufficiency, sprinkled with great times and music!!
Living vicariously through you!
(Of course I don’t know crap about the issues and technicalities)
Incredible video! Nothing more satisfying than doing things yourself. I'll definitely use this for a future build. Thanks
You could charge your big battery directly using existing solar panel by only adding solar charge controller, this way you don't have to carry a additional portable power bank. Also this all should be more efficient
yeah I'm not sure why he didn't just rig it to use the one pack... why carry a whole separate battery pack and charge it separately? also why mount the battery pack at the back of the trailer furthest away from the motors which requires a longer cable at more loss. you also have the whole underside of the trailer to attach it to. in fact if you built the battery pack to be flat instead of a brick you can fill the space between the trailer frame with battery and then the weight distribution would be better. also in terms of weight distribution it would help the overall stability of the bike to have slightly more weight over the front wheel to help keep it down on steep climbs, although that kind of depends on how heavy the hub motors are compared to the trailer. for that matter you could put hub motors on the trailer as well although to do that you might have to double the battery pack.
@@better.better Pretty sure the box came as a kit with the solar panel, also it converts everything to AC and USB power for him which he would have needed a box for inside the camper regardless.
@@swecreations He also mentioned he can charge the lithium battery pack through the portable battery though it’s not very efficient. Carrying a separate portable backup battery w/ solar makes sense for a travel camper providing a variety of charging and power outlets for other devices. For long range use seems like he’ll need to carry some extension cords and adapter.
@@better.better He said he wanted to use the bigger battery for possible other projects. So thats why he mounted it to the back and put it in that case so he can move it from project to project. If it was permanently to the trailer then he couldve easily mounted it to the frame under.
Loving this series, keep it up! Maybe version 3 could have a stained interior, a locking door, curtains, carpet, and a swamp cooler now that you have electricity! Also yeah a vent at the top would be good for circulation
This was super cool to watch, thanks for taking the time to create and share.
Watched the entire thing and was surprised by the subscriber count. Could’ve sworn this channel was above the millions already, confident he’s going to reach it by the end of the year.
Awesome! With people like you, the world will only get better. Thanks for sharing a truly inspiring video.
Yes one day we will all be hobos living in a tent, pulled by a bike.
Yeay America can indeed get lazier
OK, I had no idea what the hell you were talking about most of the time, but your explanations were flawless, your camera work good, your build outstanding, and overall I was fully enthralled and entertained for a solid half hour.
Thank you very much !
My idea to improve on this further is, to make trays that fit in the frame of the trailer to hold the batteries underneath. Could be deep trays to have them vertical or shallow and lay them on their sides in rows and then you could do multiple battery packs that are about 2× the size you made already. Also can keep them removable.
Great job! Very proud of how you got this all set up, I wish I had something like this set up for myself!
Drew you have all it takes to have a great life, thanks for sharing your passion, as we can see you are all-around talented. This kind of video inspires anyone to go at it and "DEW IT" ! I just completed a 704 KM trip in 52 hours pulling my Raleigh trailer rated for 100 lbs. Montreal to Kingston up to Ottawa and back to Montreal. This was an amazing journey 100s ok K in the trails across Ontario, the wild life was worth all of my while. Using a CYC X1 Stealth Mid-Drive motor on a converted Trek 29" MTB and to power it up I carried my load of power a mix of everything 1x72v20aH 1x72v15aH 2x52v20aH 1x48v10aH (around 5100wH) yes heavy. Plus camping gear. The week prior I did Montreal to Lévis crossed to Quebec and back to Montreal 615 KM in 39 hours. Now I know how to and where to get my recharge/break time so I can use more power and do a faster ride. It's funny when I passe other cyclist, some of them react in a way that they need to repass you and get in front so I just give it a FULL JOLT passe em again and let them know it is no use getting in front of me. After this ride I need to pull the break pads out and put some new ones. Mabe i'll cross you on a journey. I would love to make amazing videos like yours, I'm learning slowly and have my channel practicing video editing of my stuff. ( I'm a novice) and work like yours gives me ideas on how to get better at it.
That’s awesome! I’m hoping to get out on a couple trips yet this summer. Not sure I’ll tackle that many kms though! Thanks for watching
I loved the way you built your camper-bike. You have the knowledge to build what you wanted and the tools to complete it. Lovely to watch all you did. 👍👏👏
Newest bike camper video coming tomorrow afternoon 🙂
@@DrewBuildsStuff will watch thx
You are beyond talented man! Thanks for sharing your life and engineering with us!
Much respect to that battery pack build, crazy how you figured all that out!
This is awesome, I can just imagine what it means to pull this unassisted! It looks much better now being balanced. You said it yourself, covering up the battery when doing the main terminals would have been safer. I would also out a breaker in - if one of the plugs cause a short it might overload the over current protection of the BMS. But all in all, I am absolutely jealous and would love to call something like this my own
I can see the difference from last video with the realignment. Absolutely cool to add solar. Excellent job! Thanks for sharing this cool project.
Thanks for watching!
I’m impressed by the number of tools and the audacity/bravery you have in wiring up the battery yourself. Lithium batteries are tricky and can be dangerous. Hopefully you don’t run into issues with that battery.
A man of many skills. Great job. Looked like a fun project. Also, great editing.
Literally just watched the original build and now I found this. Awesome
Yeah same here 0.0
This, this is literally what I've been looking for... A bike trailer camper that went about 50 miles a day electric...
I would make it charge on solar.. add 2-3 longer term camping amenities... But this is what I been looking for
It went 29 miles or 47 kilometers
@@thespook1482 he said 44km each way…
I do not understand much of what you are doing but I like the way to slowly and carefully explained each step. Good work.
Fantastic engineering and craftsmanship! Bravo!
I would recommend a simple suspension on the trailer. Maybe some large spring, something to absorb the vibrations. This will reduce the stress on the trailer and the batteries.
good idea, was trying to keep the weight down to see how it would handle first so didn't want to get too carried away. Light weight camper build coming up next!
why do you believe he needs to reduce stress on trailer or batteries?
@@rb-ex or the gf travelling on the back... just saying ;)
@@rb-ex given all the feedback on the custom battery; my thinking reduce the vibration, then less stress on the battery
@@stevehartmann8560 right, you already said that. my question is why do you believe you need to reduce stress on the battery?
great video and gives an incredible insight into what is achievable with some good old ingenuity. Your trailer concept would be interesting if it was adapted to being towed with a small petrol powered scooter or small motorbike . Obviously it would need to be more robust with some form of springs to take some of the jolting out of the suspension but the concept of a small form factor trailer camper that can be towed with a motorbike or scooter seems a viable method of seeing the countryside at a minimal cost.
Got to say this is a pretty impressive build. I love the set up and your overall build and skills were very well done Keep up the great work. Awesome video!👍🏼🤩🫡🫡
Very nice build! As a retired master electrician I build power packs with inverters from 400w to 5000w. My latest project was a diy solar powered outdoor sauna.
This is amazing! Even more awesome than the first video of making this trailer. Well done!
Thanks for watching 👍
This is awesome! This is honestly where the future is! We need less sales and more understanding of proper tech that helps people live healthy!
Well, my guy, I am blown away. This is freakin cool!
Love the video / documentary! This is absolutely INSANE!
freaking awesome, thank you for your time and effort to make the trailer and to film the video! I would love to see you try to building a small self sustained trailer/camper that can be towed with a car/suv/truck and to have more features: like AC, Heater, water supply, Cooking and sleeping accommodation for 2+ people
If you love your bike, put a piece of inner tube between your trailer mount and your stay, and on the other side put rubber washers between the steel washers and the stay. Aluminium work hardens with flexion, then it becomes brittle, then it cracks, in that order. The bar you welded is better than a single bolt hole, but not a lot better since it doesn't allow for spin-out pitch rotation, which the original did allow (unwanted, but when happens it spares your bike frame - mitigated failure mode.) You've spread the force over an area that the aluminium can support (KSI), but it isn't steel, so shocks work cumulatively towards failure. The tube/rubber washers will eliminate a portion of the shock.
I dont have your knowledge, tools and skills but I watched it all because it is great.
You have done a great job with great skill and effort. And the place is amazing, green and green. Best area.
Love your build and your youtube movie....all very inspiring ! Most of the outer wheel supports out there are rectangular constructions. An angled front bar however could work as well as a deflective wheel protector...and looks better !
Looking forward to your improvements.
Definitely a couple minor things I would change. I would absolutely change it up to not have to carry that power bank. Maybe an MPPT would be able to make use of that 12V solar pannel, but if not you could make a small 12V lipo cell, and use a 12-48 boost converter to charge the 48V battery. Set that up to let the 12V charge all the way then discharge into the 48, you could have near unlimited range, and you could get a 48V inverter for your 110V needs.
The other change I'd do is mount the battery on the bottom. Unless you plan on some serious rough terrain it won't ever hit anything and also won't bake your bats in a black box in the sun.
Great job! Thank you for all the work you put in to it!
This was a really fun build to watch. Nice work!
I make little projects during my free time and always love seeing these videos it is really giving me motivation to keep going!!!! Good job keep up the great work
Thanks for watching!
Awesome work~ Very impressive ~ Love the music, especially during the battery build. The sci-fi vibe fits perfectly ~ This channel will continue to grow with quality content like this. Keep it up!
Thanks for watching! I have lots of ideas left for videos yet so hopefully you are right 🤞
The sheer amount of patience you need just to make the battery alone is insane
Drew, your life in Canada 🇨🇦 is really amazing!
22:50 the brake levers are also what are used to tell the controller to use its regenerative braking.
Regen braking isn't as effective with light weight devices, so I wouldn't really mind it myself.
on straight, level roads like we are shown in video there is no braking, but in more hilly terrain there could be a lot of regen going on
I like how this adressed what was the main problem of most people with the first video.
I think the only things you could improve are better left for a rebuild at some point.
Thanks for watching!
That’s the coolest electric bike camper iv ever seen. I would just line that seat with a cushioned pad and then cover that with a full woollen pelt. 👌
Outstanding, I watched entire video enjoyed every minute of it. Thank you so very much for sharing my friend.
These projects are so impressive, keep up the amazing work!
Thanks for watching!
another great video! one of the few channels i can sit for 30 minutes and not be bored
Glad to hear it! Really wasn’t sure how the 30 minute build videos would go
I think you project went really well. Great job.
Great workmanship, cool design and interesting additions like solar charging.
Great build, yeah you could of done things differently, but all in all sturdy and good range for fantastic price in the set up. The 2 battery system is genius. The hub drive is a good choice too, with the mid drive its more efficient but you have the chain wear to worry about so its a bit of a trade off.
Sleeping up off of the ground is very comfortable when camping. You could always throw a tent in it for space.
The only drawback is the wieght of the thing, but it won't be thrown around in a bit of wind either and once in motion you're just using energy against wind resistance. So plenty of trade offs.
Top notch. 5 out of 5. Superb!
You'll be happy when you get caught in a squall, and your nice and dry in your shelter.
My god this was fun to watch. Watching this come together was so compelling. Good stuff.
Thank you!
So informative haha … and the the mini festival .. that’s pretty fire man .. I def do this as soon as I can this is the new idea and or way I want to go with my plan on doing this .. thank you very much bro and dig the music
very high quality video, good explanation, and story telling, thank you!
The battery you made looks a master piece, was like watching an artist at work
Sadly, it only looks that way to people that really don't know how to build a safe battery safely. There are a few things missing as Michael Piekunka's popular comment explains.
Great stuff thanks for sharing, it's great to inspire others like you do.
If I were to build this myself (i'd be much more expensive lol), i'd start with a good enduro ebike that's fun to ride once I reach my destination, and the battery inside the caravan would be the same kind so again, once I reach my destination I can ride as much as I can. Also I'd skip the solar pannels for multiple parallel chargers.
Looks like a wealth executed endeavor. Excellent video.
Looks like a great time dude!!!
I really loved this build. Well explained and a great execution. Really would love to build a trailer for my ebike myself
What a precious work! Thanks for the inspiration, I will definitelly use your project as a template to improve my solar traveler cargobike with the big battery and the camper I need. The only thing I would change is the direct drive hub motor which produces a very frustrating amount of drag immediatelly when I stop throttling, when I pedal with the motor off or the battery is depleted ....is like having a half flat tire! and also it's sad not being able to use inercy. SO my next step is to buy a geared hub motor instead.
Just found this amazing video. Loved the project. Thank you for sharing.
I'm impressed, I love innovation like this.
That intro deserves a nobel peace prize
Love this, gonna try and make the peddling one with my dad for when we go camping! Love watching your channel! ❤️
Good luck! Let me know how the build goes. 👍
@@DrewBuildsStuff Will do! 👍
Nice work and thank you for the details 👍 enjoy your ride
You crack me up Drew! God bless you!
7:40 : The capacity of a cell is measured by discharging. The actual capacity of the cells will be considerably different to what you measured when charging them. And if you even want to get an even more real-life-value, you should discharge the cell with the same load (Ampere) as it would face in your specific case. Cheers!
@The meme windows You noticed - and maybe other users do, too. So that's fine :-)
@@thememewindows6240bit of a daft thing to say, the video poster even mentions in this video how he used information from another users channel to help with this, not everyone is completely narcissistic and self obsessed.
This was AWESOME! I'd love to have something like that. I have a Schwinn and a scooter - what a great way to travel about. Nice work, impressive.
Thanks for watching!
I salute you for your technical knowledge and skill. I'm so jealous.😄😄😄👍👍👍
Love your build,this IS a fantastic Idea and very inspiring
Soooo awesome. If I remember correctly, I think I commented to make this electric on the original video. I'm even more inspired to make something like this. I'm very curious to see how the solar panels work. I love how if it ever starts raining on your ride, you can just park and hop in the back! My only recommendation would be to swap that hub motor out for a mid-drive system motor. That way you can use the ratio of your gears with the motor.
Thanks for watching. Ya I had thought about that but since this was my first ebike I thought I’d try to keep it as simple as I could
There's trade offs either way. The downside of the mid drive is the additional stresses it puts on the chain and additional wear and tear of the drive system. One advantage of the hub motor is redundancy. If you snap a chain it doesn't matter, you still have the motor to drive the bike. Honestly his bike is probably better off with a hub due to the additional weight being hauled.
I wonder if he should add brakes to the trailer. It's asking a lot of two wheels to stop, especially on a downhill road.
@@jtalbainWSA if he were in a more hilly area, I would recommend he add a switch to plug into the cables that go to the breaks, if the controller supports regenerative breaking it can act as a retardation break before actually having to use the disk breaks.
You might to revisit using the brake levers.
They often trigger regen braking first. Since your rig is pretty heavy there is a lot of energy to recover potentially.
Also, your band sounds great.
There is a HUGE VESC community ( Modders for OneWheel's ) that can help with the software programming with Regeneration of Energy back into the cells.
@@lostphotographs3936 OneWheel is based on VESC from the factory?
This is an absolutely awesome build. Great work. 👍 subscribed.
Just love your videos Drew...keep up the great work!!
This is fantastic! Consider yourself +1 subscriber sir!
The only observations/suggestions, would be to hook your rear lights up to the external battery as well, so you don't have to worry about those going out, and upgrading your brake setup.
I'd imagine with the weight if you're going downhill, that thing has some momentum. Perhaps some bigger callipers and discs as well as considering upgrading to hydraulic brakes (and potentially larger/gripier tires).
If you could fit brakes on the tralier as well, all the better.
Sturmey Archer made trike wheel hubs with internal drum brakes that would be perfect for a trailer build like this. the X-SD model comes to mind.
I know that if I was lugging a 60kg+ trailer up or down a hill I'd certainly want that trailer to have an independent braking system...
Congratulations, you sure have a lot of talent in many different areas. Hope all your hard work and planning, allows for many miles with your Newly battery powered bike and trailer.
Thanks Ben!
Made a few ebike, s. Myself, must say very impressed by your work 👍
Drew, your work just like 👍 your camper is so elegant your skillful man...
What a great build, thanks for your detailed video! Just fyi, the flexible solar panel you used will degrade much faster being glued directly onto the surface of your roof. I have seen them bubble up and severely delaminate when surface mounted. To avoid this, a light and simple frame that gives it about 1-2 inches of airspace below will allow adequate venting of heat, preventing damage to the cells/laminates. Thanks again, great work!
Flexible panels are meant to be fixed directly to a flat or curved surface, that's why they're flexible.
@@markrainford1219 I believe the worry here is heat regulation not mechanical wear. Rather, the question is whether the roof is sufficiently cool. A space would allow airflow, and possibly insulate the solar panel-roof connection. Weather that would help ain't in my knowledge.
Cheers
The last time i researched flexible panels, all had short lifespans. No expert vouches for them. Most advised to avoid them because of high failure rates. All DID stress the need for air space. Most use wood dowels.
Just a thought, but powered wheels on the trailer and containing all the electronics in the trailer would seem optimal. You can then detatch your bike and use it as a bit, with just few switches and connectors adding weight.
Just wanted to say that you’re a Genius 👌👌👌
You are quite the craftsman young man 🚴👍
You could probably fit Renogy's 175W flexible panel on the same space as the 100W you installed. They now have a 200W flexible. Big difference!
